WebJun 30, 2024 · A specific amount of energy is needed to promote electrons in a substance to a higher energy state which we can detect as absorption. Electrons in different bonding environments in a substance require a different specific amount of energy to promote the electrons to a higher energy state. WebSpectroscopy is the study of how radiated energy and materials interact. Matter absorbs energy, which will create some sort of change in its state. The atomic part refers to the atoms in a material, which will absorb radiated energy from a light source.
